I suspect that your battery has developed a slow discharge due to internal shorting. This is one of the common failure modes of rechargable batteries. If it really is hibernated then it should be virtually zero power (only enough to run the power button). You can remove the battery. To test this theory I would either hibernate or shutdown and remove the battery then test the power level again after an overnight. If the power is the same as before then your battery is probably okay and the fault is elsewhere. If the power is drained with the battery removed then you can be fairly certain that the problem is isolated to the battery. Hopefully that is it because then you have an easy, if moderatly expensive, fix and then you are back solidly running again. It that isn't it then I have no more ideas. Good luck! Bob
